Using the Smarts 6.x installer, this is how you can specify the location of the log file. The installation normally puts the log file in a temporary location which it copies to the BASEDIR on success, then deletes the original. However, if the installer bombs out, it just deletes the original, leaving the user with nothing. Here is a way to specify another location for the log file, which the installer will leave behind:
<install_image> -log # !<logLocation> @ALLExample:
setup-winnt.exe -log # !C:/logfile.txt @ALLor
setup-solaris.bin -log # !/tmp/logfile.txt @ALL
The '@ALL' means to capture all events.
